Please help with Radiator Fan running all time / no heat

Please help
My drive belt & pulley broke.
I did drive the car some and it did go into the red to shut off.
Today I changed pulley & belt but, after start up the radiator fan kicked into high gear & not shutting off until 2-3 minutes after key removal.
Plus no heat.

Please help as I have my mother In-law's funeral on Thursday and need to fix this.

Fan system needs to be tested in star/ das. It could be many things. The fact that you cooked the engine a bit doesn’t help either and might complicate things a bit.
